Application tiled June 30, 1913.

T0 all whom fit mog] concern:

lle it known that I, lViLLian K. lon'rnn, a citi/.en of the United States, residing at Pittsburgh7 in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in indicators, of' which the following is a speciiication.

The present invention relatos to improvements in indicating` devices particularly adapted I`or designating the naine of the next street, station, or stop for railway trains, street cars, subway trains or the like. It. will be obvious, however, this description proceeds, in its broad sense the invention is susceptible o'l. various uses,sucli, for instance, as when located at a station to designate or announce the destination, route or direction oit the next arriving train or public conveyance.

To the end ot accon-iplishing the abovepurpose, the deViceconiprises essentially certain web rolls to"li.old and receive an indicating web member or`4 curtain in combination with feeding mechanism adapted to be intermittently operated so as to carry the Tweb trom one roll to another and to disclose the indicia thereon, regulating` means being employed to govern the extent ot intermittent, movement ot said web.

A further object ot my invention is to provide cooperating tension mechanism tor the web rolls, whereby movement ol both holding,Y and receiving' rolls may be suitably controlled, oneto wind np the web and the other to pay out the saine in a retarded manner to insure proper travel of this indieatingl member.

Still another object in mind is the proviv sion ot reversingmechanism whereby the direction oftravcl oi the web aforesaid may be readily reversed, accompanied by simultaneous reversal oi the feeding' and tensioning' niecbanisni justJ mentioned, and in conjunction with this, novel means capable in one positionof locking` the various mech-1 anisin :tor proper operation when once set and in another position of braking or locking against.- operation the tensioning mechanism duriing the reversing action.

lt is also contemplated to employ a route indicator in connection `with the 'foregoing f which is automatically operated during the actuation ot the reversing.,T mechanism.

With the above and other objects in view,

this invention consists in the construction,

combination and arrangement ot' parts all Paten-ted it't, serial nel *7i/e662.

as hereinafter more fully described, claimed and illustrated in the acconipanying; dravvings, wherein i Figure l is a perspective view showing the mounting ot a device constructed in acordance with my invention,upon its supporting bracket.

Throughout the following detail descripu tion, and on the several figures ot' the draiv- Elli titi

ably inclosed in a suitably shaped casing designated vby the numeal 1, access tol Which is gained through inc door at thtl top of the same7 the latter being hinged at the rear portion ot' the casing as indicated marked with the words Next street the name of ivhich appears through the glass l The casing` has also l panel 4t therebe'neath. 'suitably mounted on its bottom spaced guideu'ays 5 which are adapted to slidably engage with the' bracket arms (3, by means of which -the device is supported at a convenient place for observation by the passengers, the rear edge portion of said casingr having bolt receiving plates 7 and pivoted ring members 8 through the latter of which a locking rod 9 passes to secure the casing rmly in place. llilithin the casingand at its front portion are mounted an upper and a lower hanged web receiving roll 10, 11, having their bearings in the side frames or standards 12, 13. Each of these rolls comprises a removable section (1,' having a plurality of openings therein to receive the studs 14 on the main body portion ot' Said rolls, the latter also havingat one end a vpivoted clamping member b beneath which one end of the sect-ion a engages, while at the other end is disposed a latch member to interlock With the hooked end of vsaid section a. It Will be readily understood from the foregoing that the Yweb or curtain 15 l bearing' the stre-et names or other indicia, having suitable eyelets at its end portions, is hooked over the studs 111- beneath the section a of one et these rolls upon which said web is to be wound, this roll being hereinafter referred to as the Web receiving roll, While the other of the rolls from which the web is univound Will be called the web holding roll, these terms being interchangeably used accordingr to the direction in vwhich the web is passing.

Feeding mec/lmigrer-Between the web rolls 10, 11 and suitably spaced therefrom as Well as from each other, are tivo sets of feeding rolls, each set consisting ot a pair of rolls 16 and 1G having intermeshing pinions 17 at their end portions. The shaft of one of' the rolls 1G ot' each set extends beyond the side frame 12 and lixedly secured to these ends are the cog- Wheels 18 around which passes a drivingl chain 19. As seen most clearly in Fig, il, this chain also passes l forwardly from the frame 12, vvhile the t'ormer is'mounted in the ljournal 1T, toi-med on tlu` Slidable erasing it and extending through the slotted arm aforesaid. "'i'i'ithin the casing' is mounted the adjusting screvv having a spring 2G adapted to be whereby the irictional. Contact or' the co operating` rolls may be suitably governed,

l 5 ed end 27 formed at its inner extremity, l

i the faces of said rolls beiner preie ably corrugated to insure positive gripping of the web l'ivhich is passed between these feed rolls on to the web receivingv rollt rlhese i feed rolls are similarly mounted at each end as will be obvious.

Returningto the description of the driving shaft Q2 which is revoluhly mounted in the upper end of thesiandard QS, thisshatt is divided, and comprises the relatively stationary portion 92a and the movable portion 2T journaled in the arm'QlT these sections having pin and slot connection as indicated by the reference numeral 30. The inner eX- tremity of the driving shai't- 92 carries a beveled pinion 31 which enga3 with the main driving gear 32 beveled on its inner peripheral edge portion 'for properly meshingwith said pinion. The true periphery of this driving .vheel or gear 32 is also notched so as to be locked against movement in one direction by engagement therewith ot' a gravitating paivl 33 mounted above said i near on a .shaft 3d projecting` rearwardly l iirom the supporting standard 35 adjacent thel inner i'ace the gear 32. rfhe drivingl xvheel or `rear 532 itself is keyed to a shaft .support fifi and uthe outer end o t this shatt` St? carries the upper end ot a stroke lever .-lT which is looselyconnected ivith the shaft in an)V desired manner. The lever 3T extends downwardly a suitable distance so as to project slightly below the bottom of the casing' 1 ivhere it is connected to an actuating' rod 31% by means of a link 39, the rod aforesaid preferably extending' transversely l oi" the casing and being suitably supported by one or more supports it). ,llurthermore the actuating` lover has pivotallyconnected thereto at a point directly adjacent the lower portion o'tf the drive gez r 32 a spring actuating paul lt which is normally held in engagement with the notched periphery ot said lz'ear.I whereby upon puttingv the rod 3S; the drive gear 32 will be moved a predotcrmiued amount`r transmitting; its motion to i the driveA shui when the partsrarc in the shown in liigr. 2. )is the. stroke ylever if, is actuated l2 carried on the lie-ade( connected to a, sliding' `guide member or block /l-t, the latter in turn beine,` connected i to the 'lever 3T by the l' l: 45, isplaced under l comprension time wuen tue rod 38 retensioned by the adjustment ot the threadl 3G revolubly mounted in the standard ou by the. pawl the spring' l rod 43 which only as it is being fed by the rolls 16 in the inanner now to be described.

One end of the roll l0 extends into the side fran'ie 12 and has formed thereon a pinion 73a which is geared by means of intei-meshing large gears 72 and sniall gears 71.u to the large gear 70a carried by the shaft (55e. The shaft as in the ease of its corresponding shaft I is divided, one portion of the saine having its hearings in the upper part of the standard 69u while its other portion is journaled in `the arm G6, said shaft also having at its inner extremity a beveled pinion' (SSH. The arin G6 connected to a slidingv bar S1 slidably niounted in the guide way 67, which bar extends beneath the ease 57 for the spring 5G in order to be similarly and rigidly connected With the arin Gti. The zguide Way G7 near the end adjacent. the shaft G9n is provided With vertieally extending` standards S2 on the top of which is mounted a semi-Circular frame SEE to support a friction brake S11- the shoe Sile being of Crescent shape so as to eonforin to the contour of the pinion GS against whiifh it normally bears ivhenvthe shaft 65 is disposed in its retracted position shown in Fig'. 2. rlllie brake S- eonsists also of a tension rod upon ivhieh is niounted a spring- 86 normally bearing against the traine S25, said rod being` threaded and provided with an adjusting nutST to regulate the tension of the shoe $5 against the pinion (iS-'K llenee it Will' he understood that as the web is pulled from the roll 10 it is retarded by the frietional Contact of the brake Si so yas to `give otf the web only as desired.

Incidental to the ronstruetion, .l preferalily provid a' rover Sh Secured to the hottoni of the easing 1 and partially housing; the innermost oder portion of the. lai-1e gear (Srl to prevent ai'feidental eontart of the well l5 therewith.

Havrais/oy mee/maism.--The foregoing deseription has set forth the niovenient of the iveh l'roni the upper to the loiver web roll suoli as would agree when the eonveyanre rarrving' the indiralor is .traversingT its route in one direetion and when the end of the line or its destination in. thatl direi-tion 4lfas'heen reached it ywill be understood the direeiion of feedingY of the web ninst be reversed so as to feed from the lower to thi` upper roll.- 'lo arron'iplish this as well as a reversal of the em'iperatinl nieehanisins of the devire, reversing nieaus is employed as ivill non' be desrrihed.

The free end of the web having been properly seeured upon the upper 'roll 1U. brine' passed. of course.. through the feed roll! 11". lo this roll now heeouies the rerrivine' roll While the roll 11 from which ihr iveh is fed will be the holding' roll.

he ilriuurqr shaft as has been stated previously is journeled at its inner portion .Y memes in` the arm Q9 which is inovably mounted in the guide way 89 which guide Way extends transversely throughout the greater portion of the easing l just beneath the standard 35 and as will be noted in Fig. 11 the arin 29 is provided With lateral grooves so as to readily operate between tongued extensions 89 of the guide Way S9 and, furthermore. this arin is integrally formed upon a sliding bar 90 which extends across the device to the opposite. end portionv of the guide ivay S9 where it has formed on its extremity a niovable vertically disposed arin 29 similar in all respects to the arni Q9. The bottoni portion of the slide 90 Carrying the arins 20 a l 29a is suitably toothed as indieated at 91 to inesh with a Worm 92 on the end portion of the' reversingr rod 93.3 ivhieh is revolubly mounted beneath the slide 90 and in the-"guide '-.vay S9. This rod J2-i passes out of the guide Way S9 at one end and across the device7 terminating exterior to the easing' 1 in a ting-er piece Q-l Ly nieansv of which the rod may be readily manipulated. ly turning the rod 93 in one direetion. the slide Slt) with its arnis 29 and 2W will be moved `guide nay Si? through the action of the vforni 5; i nd the meshing' teeth 91 until the near 3l is out of inesh with the drive vo 'ear $32. he movable sertion 22D of the shaft permitting by rea-wn of the and sint ronneriion 3i) this disengae'e taueoualy with the filing: ,i pinion 'l from the nner-l l2 the arin Q9" brings the divided .sei-lion Qi `of the shaft 22" with 'hirh the foriner has pin and slot ronneetion at 220, toward the drive wheel P12 until the pinion 3l at its inner extremity engages with said drivev'heel 32.A The sta- .ver-tion of the shaft 22d is journaled atithe lop of the standing QC. Obviously nioiion' imparted to the `Wheel 32 will be transmitted through the shaft- 221 to the lai-ige sprocket wheel 2l whence it is conveyed hy the rhein 1S) to the con` Wheels 18 rarried hy the ends of the feed rollers 16 at the opposite side of the device to those :mais herrinbefore mentioned. These feed rollersare thus Caused to rotate in an opposite dirertion to that. formerly described-so thatv the web is positively fed upwardly from the roil l1 to the roll 10. Obviously the tension formerly exerted upon the roll 11 h.' the spring' 5G nnist now be transferred toy the roller 10 and to this end the reversing rod 923 is provided with a beveled gear 95 nraihone end of the `auide Way S9 which .iear naeslies with a corresponding gear 96 rarried hv the end of a longitudinal shaft ffl" extending towardthe forward portion oi the deviee and mounted in suitable bearings DS on the bottom of the easing l. The opposite end of the shaft- 97 carries a beveled gear 99 meshing with@ similar gear intranet 100 oli a, short transverse shaft 101. r1`his latter shait't is provided with a Worm 102 which meshes with teeth formed on the bot tcm ot the slide S1 which :arrics at its ends arms 00 and 00 respectively. 1n this inanner the movement el the reversing rod 93 will cause the slide 8l to :arry the arm G0 with the lt'me'itudinally movable section of the divided shaft transversely of the device until the pinion GS is brought into engagementivith the peripheral gear teeth on the disk til. simultaneously disengaging the pinion ($53 'from the oiiposite side oli the gear t'rlby reason of the movement of the arm ttt) in the ruido way 07 Ywhich carries the divided sha'l't 35. 1t will be understood that the movement ot the divided shatt relieves the baliing.; action against the pinion n'hile the pinion (38 is broght into contact with the bralie Sltzi carried by the standard S2 which brake is similar in all respects to that described with reference to the brake Srl. The tension ot the spring 'in this nianner is carried through the divided shat't 0.3@ and through the train oit gears 70, ilfmand T2 to the pinion T3 on the end ot the .veh roll 10 and on the contrary retard infr action has now been tra'nsl'erred to the roll 1l due lo the action ot the brake Sil on the pinion (Se carried by lthe shaft 05, through the instrumentality ol" the train of nears T0, Tl. and 72 to the pinion i3 on the short shaft Tl. and :from thence tl'n'ounh the shalt 'Z7 geared to the latter at one end and to thel web roll l1 geared to its other end.

Lcd, ng meelmnfsnawln order that no aceidental movement ot the mechanisms may occur in their positions as have been set forth, 1 provide means tor locking the cotn'ierating` parts such t'or instance as when in the position shown in Fig. Q, just described. 1n this `ligure it will be observed that lockingrod 103 is disposed on the guide way 89 and at the tirent side of the same which rod has formed thereon in spaced relation to each other sets of projections 101 which projections are adapted norn'ially to engage in notches 105 termed on the ;l or wird and lateral portion ot' the sliding bar 00, a sullicient nurhl'ier of these notches 105 being' provided to give a certain amount of latitude ot locking engagement with the -teeth 1011 so as to insure the proper positioning oit the -n'iovable sections 221 and 224 ot the shat'ts 22 and 9.2d,respectively. `When it desired to reverse the operationl o1! the web a .luunlle 106 carried by the outer extremity ot the locking rod 103, exterior to the easingl '1 is pulled forwardly until it loclringrly engages with the bent end portion ol a resilient arc shaped member 107 secured to the side ot' the casing` 1 as shown in Fig. 4. The teeth 10ft are thus disengaged from, the notches 105 so that the reversing; rod 93 may be operated until the reversed position iso obtained, but di'iring;` the reversing action the tension o'l the springj)` is held inoperative by a brake secured to one side of the locking' rod 103 which engages with the large horizontal gear (31. This brake consists oit' a curved arm 10S connected at 109 to the rod 103 and at its other end through a linl; 110 to a plunger rod 111. This rod is placed under tension by means o1? a spring 1,12 against which spring the plunger presses in the normal inoperative position of the brake. The tree extremity oit the rod 111 carries a brake arm 113 ha vint;Y a triangular projection 1111 adapted to engage With the teeth. ol the largo gear 01 when the locking rod, 10i-5 is moved into the position Yjust described. This gear is then held from movement under the actuation of the spring` 50 until the handle 10G is moved rearwardly to engage in the detent portion at the opposite end ot' the resilient member 107, this latter position engaging the teeth 101 with the notches 105 on the slide 490.

(2c/neral summaryf-lhe operation of the device will have become apparent from con sideration of the foregoing description and it may be generally stated in conclusion that Iwhen the conveyance carrying the indicator device comprising; this invention is about to be started upon its route the conductor'or other operator sets the device properly for indication. To do this he lirst secures a key 11,5li'om a compartment 110 conveniently Yformed in the casing 1. placing' said key on the squared end Q2@ of the shaft 22 which projifets exterior to the easing 1 turning.` the shat't until the name ot the lirststreet onthe web, the ilree end oit which has been previously engaged with the receiving' roll, comes opposite the lglass 1. lt is assumed, of course, that the stroke regulator has been properly set in order that the actuation of the web will bring the next name on the same to this position. At a. convenient point ot tavel -of the conveyance the conductor will pull a strap which is secured to a ring 38 on the tree end of the operating' rod 3S, thereby actuating the gear S12 so as to move the web at fr single stroke to the proper position for the next named street. This intermittent operation o1' the Web continues until the end o1 the route is reached 4when the operation reverses. Before further manipulation the operator must move the handle 10G on the locking' rod 103 so as to unlock the mechanism, whereupon the rcversing; rod 93 is manipulated so as to reverse the driving shafts and shafts controlling the tension on the web rolls. The reversingl rod 93 having' been turnedvits limit the handle 106 is moved into its normal or initial positionand the device is ready again 'for intermittent operation to indicate the streets in their reverse order to agree Awith the direction.
